TROUBLESHOOTING
Road Test
This test is to check if upshift and downshift take place at specified speed while actually driving vehicle on a
level road.
1) Warm up engine.
2) With engine running at idle, shift select lever “D”.
3) Accelerate vehicle speed by depressing accelerator pedal gradually.
4) While driving in “D” range, check if gear shift occurs properly as shown in “GEAR SHIFT DIAGRAM” in this
section.
TROUBLESHOOTING
Condition Possible cause
Line pressure higher than standard level in each
range•Malfunctioning regulator valve
•Malfunctioning throttle valve
•Maladjusted A/T throttle cable
Line pressure lower than standard level in each
range•Defective O/D clutch
•Defective oil pump
•Malfunctioning throttle valve
•Malfunctioning regulator value
•Maladjusted A/T throttle cable

Manual Road Test
This test check the gear being used in “L”, “2” or “D” range when
driven with unoperated gear shift control system. Test drive vehi-
cle on a level road.
1) Disconnect shift solenoid coupler (1) valves on transmission.
2) With select lever in “P”, start engine and warm it up.
3) With select lever in “L” range, start vehicle and accelerate to
20 km/h (12.5 mile/h). Check in this state that 1st gear is
being used.
4) At 20 km/h (12.5 mile/h), shift select lever to “2” range and
accelerate to 40 km/h (25 mile/h). Check in this state that 3rd
gear is being used.
5) At 40 km/h (25 mile/h), shift select lever to “D” range and
check that O/D gear is used when speed is higher than 40
km/h (25 mile/h).
6) After above checks, stop vehicle then engine, and connect
shift solenoids coupler (1) with ignition switch OFF.
7) Clear DTC with scan tool.
Time Lag Test
This test is to check conditions of clutch, reverse brake and fluid pressure. “Time lag” means time elapsed since
select lever is shifted with engine idling till shock is felt.
1) With chocks placed before and behind front and rear wheels respectively, depress brake pedal.
2) Start engine.
3) With stop watch ready, shift select lever from “N” to “D” range and measure time from that moment till shock
is felt.
4) Similarly measure time lag by shifting select lever from “N“ to “R” range.
Specification for time lag :NOTE:
Before this test, check diagnostic trouble code (DTC).
WARNING:
To avoid the danger of being burned, do not touch the hot
exhaust system when disconnecting shift solenoid cou-
pler (1).

Fluid level
LEVEL CHECK AT NORMAL OPERATING TEMPERATURE
1) Stop vehicle and place it level.
2) Apply parking brake and place chocks against wheels.
3) With selector at P position, start engine.
4) Warm up engine till fluid temperature reaches normal oper-
ating temperature (70 – 80 °C (158 – 176 °F)). As a guide to
check fluid temperature, warm up engine till engine coolant
temperature meter indicated around 1 unit above “C” point.
5) Keep engine idling and shift selector slowly to “L” and back
to “P” position.
6) With engine idling, pull out dipstick, wipe it off with a clean
cloth and put it back into place.
7) Pull out dipstick again and check fluid level indicated on it.
Fluid level should be between FULL HOT and LOW HOT. if it
is below LOW HOT, add an equivalent of DEXRON
®-III up to
FULL HOT.
Fluid specification :
An equivalent of DEXRON
®-III
[A] : Shift the select lever with its button pushed in.
[B] : Shift the select lever without pushing its button.
NOTE:
DO NOT RACE ENGINE while checking fluid level, even
after the engine start.
DO NOT OVERFILL. Overfilling can causes foaming
and loss of fluid through breather. Then slippage and
transmission failure can result.
Bringing the level from LOW HOT to FULL HOT
requires 0.3 liters (0.64/0.53 US/lmp.pt).
If vehicle was driven under high load such as pulling a
trailer, fluid level should be checked about half an hour
after it is stopped.

Diagnosis
Diagnosis Table
PCM – Overdrive and TCC
off command signal outputWhen the throttle opening for the vehicle speed exceeds the specified value
during cruise control, the cruise control module sends this signal to PCM. PCM
uses this signal as one of signals to control 4-A/T.
Cruise main switch indicator
lampIn the state with the ignition switch ON and the cruise control system OFF,
pressing this switch once and releasing it will activate the cruise control system
and the cruise control module will cause the indicator lamp to light up.
“CRUISE” indicator lamp It lights up when cruise control (accelerator pedal control) is functioning. Component Function
NOTE:
When constant cruising is cancelled under above any condition with * (asterisk), vehicle speed before
cancellation can be resumed by operating ACCEL RESUME switch, provided that vehicle speed is
higher than 40 km/h (25 miles/h).
